A look inside the Cisco DevNet Professional study guide

Learn how network automation works with software development in this chapter excerpt from 'Cisco Certified DevNet Professional DEVCOR 350-901 Official Cert Guide.'

Most network practitioners have heard it's time for a mind shift.

More than ever, traditional networking now intersects with principles and concepts that challenge the standard way of doing things, due to the growth of software, programmability and automation. For network engineers up to the challenge, the Cisco DevNet Professional certification track provides a useful way to foster the skill sets that support evolving networking strategies.

The DevNet Professional certification targets more experienced network engineers and requires candidates to pass the core DEVCOR exam in addition to a concentration exam, covering specializations like IoT, unified communications and security.

When pursuing any certification, exam candidates should construct a study strategy. The authors of the recently published Cisco Certified DevNet Professional DEVCOR 350-901 Official Cert Guide, from Cisco Press, said they hope their study guide provides guidance in building that strategy. Authored by Jason Davis, Hazim Dahir, Stuart Clark and Quinn Snyder, the book acts as a launch point for readers to assess what they already know and dig into the topics they don't.

"You can pass a test. But we want to give you a way of thinking where you can gather the requirements [for the exam] and, based on those requirements, build a strategy," Dahir said.

A mindset change is crucial for candidates studying for the DevNet certification because of its shift from legacy networking principles to a focus in software. For example, candidates studying for other networking certifications, such as Cisco Certified Network Associate or Cisco Certified Network Professional, often work with the same gear they're learning about during their day jobs, Snyder said. But, with the DevNet track, most engineers don't encounter the software development lifecycle or write code in their current roles, requiring a conscious effort for them to practice those principles, he added.

Below is a chapter excerpt from Cisco Certified DevNet Professional DEVCOR 350-901 Official Cert Guide: "Automation." This chapter explores topics like the software development lifecycle, APIs and network programmability.
